【组合数】2024-3-16

缘由C语言组合数，多组数据处理_编程语言-CSDN问答

int 组合数(int n, int m)
{//缘由https://ask.csdn.net/questions/8074182
	long long nj = 1, mj = 1, nmj = 1, nm = n - m;
jc:if (n)
{
	   nj *= n;
	   if (m)mj *= m, --m;
	   if (nm)nmj *= nm, --nm;
	   --n;
	   goto jc;
}
   std::cout << nj << "/" << mj << "*" << nmj << "=";
   return nj / (mj * nmj);
}

我以此施而自庄严，不求人天无常，愿真正无上道成，若获无尽宝藏施无逆意。
